v VENTILATING SYSTEM.

Specification of Letters Patent. Patented lay 30, 1911 Application ledOctober 19, 1910. Serial No. 587,895.

l i I do hereby declare the following to be a full, clear, and exactdescription of the invention, such asI will enable others skilled in theart to which it appertains to make and use t-he same.

The present invention has relation to veni tilating systems.

difficulty has been experienced in properly Ventilating street carsduring the winter season, owing to the fact that the car windows areclosed during the entire time the car is in service, and that in manyinstances, storm windows are used in addition to the ordinary windows.

It is the object of the present invention, therefore, to provide asystem of Ventilation which, when installed, will insure the admissionof a continuous supply of pure air into the interior of the car an atthe same time, will effect the discharge of the im- Heretofore, great.pure air therefrom.

such as Another object of the invention resides in the revision of asystem of ventilation of nove character which may be used either inconnection with cars as above noted or in the ventilation of otherchambers such as rooms in offices, dwellings and the like.

"Io this end, the invention consists in a novel construction ofVentilating system' adapted to be applied to closed chambers have beenabove described and especially adapted for application to street orother railway cars.

A still further object of the invention is the provision of means ofnovel character for effecting the continuous admission of pure air intothe chamber, the air thus adgiitted serving to cool the ventilated cham-The invention further consists in the construction, combination andarrangement of parts, all as hereinafter fully described, speeificallyclaimed, and illustrated in the accompanying drawings, in which likeparts are designated by corresponding reference numerals in the severalviews.

In the drawings, Figure 1 is a longitudinal vertical section through acar equippedI with the present Ventilating system. Fig. 2 is an innerplan View of the car roof,

showing the disposition of the Ventilating pipes and tlues. Fig. 3 is anenlarged detail View, partly in section, through one of the Ventilatingpipes. Fig. 4 is a longitudinal section through the fan casing. Fig. 5is a transverse section on the line 5-5 of Fig. 1. Fig. (3 is aperspective View of the funnel member forming the end of the fan casing.

Vhile the invention is adapted for the ventilation of other chambersthan car bodies its specific application to a car has been' herein shownand described but it is not to be understood that the invention islimited to this precise application.

The car shown in the drawings is of the ordinary type in use on streetrailways, and includes the front and rear platforms 7 and 8, disposed atopposite ends of the car body 9. Both platforms are partially in-`closed, as is customary during the winter season, and in the front wallof the forward platform there is provided a Ventilating opening 10,covered by a screen 11 of wire gauze or similar material.

Into the Ventilating opening above referred to, extends one end of anapproximately cylindrical casing 12, in which a rotary fan 13 ismounted, the fan being operatively connected with the car motor (notshown). The rear end of the casing is formed by a funnel shaped member14, in whose smaller end a series of openings 15 are formed, in each ofwhich is fitted the front end of an air pipe or flue 16, which extendsthrough an opening formed in the front wall 17 of the car body, and isheld in position by depending straps secured to the car roof. The funnelshaped member 14 is further provided with openings 19 somewhat largerthan the openings 15, one end of a flexible pipe 20 being fitted in eachopening and extending through a similar opening formed in the front wall17 and provided at its opposite end with a flared' or funnel shapedmember. As shown in Fig. 1, the several fiues 16 and the inlet pipe 20are disposed above the top of the door 18 formed in the wall 17.Disposed within the interior of the car body is a series of pairs offunnel-shaped ventilators 21 each of which is provided with a verticalstem 22, the stems of each pair uniting as at 23 and the united stembeing connected with a longitudinal pipe 24 eX- tending beneath the carroof. This pipe 24 is carried to the rear of the ear and passes outthrough the roof in a goose-neck 25. The lower parts of each of thestems 22 are connected by a brace pipe 26 which does not communicatedirectly with the stems but which is connected to a respective pipe 16.From this pipe 25 extend blast pipes 26 which are carried down aroundthe necks of the respective funnels and extend up a slight distance intothe stem. In the present instance four pairs of ventilators are shownwithin the car body, and the end member 14 of the casing 12 willtherefore be provided with a corresponding number of flue open'- ings.It will be understood, however, that the number of ventilators and fluesmay be varied at will.

It will be apparent from the foregoing that when the fan 13 is set inmotion air will be drawn through the Ventilating opening 10 and forcedthrough the member 14 and the ues 16 connected therewith. The passage ofair through the flues will effect a forced draft in connection with eachventilator, so that the impure air within the car body will be drawnupwardly through thc several ventilators and will pass through theirstems to the exterior of the car. Simultaneously with the removal ordischarge of the impure air a continuous current of pure air will beforced into the car body through the inlet pipe 20, which is likewiseconnected with the funnel member of the casing 12. Each Hue, inpractice, is provided adjacent its discharge end with a valve 27, bymeans of which the passage of air therethrough to the correspondingventilator may be regulated.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of this invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described, but it is wished toinclude all such as properly come within the scope of the appendedclaims.

What'is claimed, is

1. In a Ventilating system, a chamber, a series of ventilators disposedin the interior of the chamber, each ventilator including a hollow stemopening out of the chamber; a casing; a series of flues each connectedat one end with said casing and having its opposite end extending withinone of said ventilator stems; an inlet pipe connected at one end withsaid casing; and a fan rotatably mounted in said casing in position todischarge a current of air through said flues,

to create a forced draft in said ventilators,

and to discharge a currentof air through said inlet pipe into theinterior of the chamber.

2. In a Ventilating system, a chamber, a funnel shaped ventilato-rdisposed within the interior of the chamber and including a hollow stemopening out of the chamber; a casing provided with an inlet opening; afunnel shaped member forming the rear end of said casing; aL flue havingone end fitted in an opening formed in said member and having itsopposite end. extending within said ventilator stem; an inlet pipeconnected with said member; and a vfan rotatably mounted within saidcasing',- 'in position to force a current of air through said inlet pipeinto the interior of the car, and to discharge air through said flue tocreate a forced draft in said ventilator.

3. The combination, in a car including front and rear platforms and acar body disposed therebetween; of a series of vent-ilators disposedwithin the interior of the car body, each having a hollow stemprojecting through an opening inthe car roof;

a casing located within the front platform and provided with an inletopening; a funnel shaped member forming the rear end of said casing andprovided with a series of openings; a series of flues each having oneend fitted in one of said openings, and vhaving its opposite endextending upwardly within the stem of one of said ventilators; an inletpipe connected with said member and having its free end extending intothe interior of thevcar body; and a fan rotatably mounted within saidcasing, in position to force a current of air through ysaid inlet pipeinto the interior of the car, and to discharge air through said flues tocreate a forced draft in said ventilator.

In testimony whereof, I affix my signature,

in presence of two witnesses.
